MO PHONG VI IEU KHIEN

I. Cac linh kien ho tr mo phong vi ieu khien: 1. Cac ho vi ieu khien:

Phan mem ISIS ho tr mo phong rat nhieu ho vi ieu khien khac nhau, trong o co cac ho c s dung thong dung hien nay nh: 8051, PIC16FXX, AT89CXX.

Cac ho vi ieu khien nay nam trong th vien Micro.

Cac ho vi ieu khien nay co s o chan va ac tnh giong vi thc te nen

khi mo phong ban nen chon ho vi ieu khien tng ng vi phan cng ma ban thiet ke.

2. Cac thiet b hien th: Cac thiet b hien th c dung e hien th so, hien th ky t Cac thiet b

nay nam chu yeu trong th vien Display.




Trong th vien Display co cac thiet b hien th sau: 2.1. Led 7 oan (Seven_Segment):

Led 7 oan co hai loai, anode chung va cathode chung. Ngoai ra trong th vien Display con co cac dang thanh led 7 oan t 2- 8 led rat thuan li cho mo phong.

2.2. LCD ( Liquid Crystal Display). Lcd (mang hnh tinh the long) la thiet b hien th so lan ky t nen c

dung rat rong rai. Moi Lcd co mot kha nang hien th khac nhau, tuy vao kch thc hay so o hien th cua moi Lcd.

Cathode Anode



2.3. Led ma tran (matrix led). Led ma tran dung pho bien trong cac mach quang bao, chu yeu la hien th

ky t. Led ma tran trong th vien Display co 2 kch thc 5x7 va 8x8 (so hang x so cot).

3. Ban phm (Keypad).

Ban phm la thiet b nhap d lieu c dung chu yeu trong cac mach mo phong cac mach tnh toan.

Trong th vien Active ban phm co tat ca 3 loai: Ban phm may tnh ( Keypad caculator). Ban phm ien thoai (Kedpad phone). Ban phm may tnh nho (Kedpad small caculator).



4. ong c( motor). Trong th vien Active co ho tr mo phong 3 loai ong c: ong c bc,

ong c servo va ong c dc. Cac ong c nay ieu co chc nang hien th van toc quay theo hai chieu thuan va ngc.

5. Ic nh (Memory). Ic nh la linh kien dung e ket noi ngoai vi ieu khien e lam bo nh

ngoai. Trong th vien memory co cac ho ic nh nh: FROM, IFROM

Stepper Servo DC



6. Bo chuyen oi DAC-ADC (Digital to analog converters). Cac bo chuyen oi ADC va DAC dung e chuyen oi t tng t sang so

va t so sang tng t. Trong th vien NATDAC co hau nh ay u cac loai vi mach ADC va DAC.

II. Cac bc tien hanh mo phong vi ieu khien:

Muc ch cua mo phong vi ieu khien la giup ta co the quan sat, ieu chnh hoat ong cua mach trc khi thi cong. Mo phong vi ieu khien con phuc vu tot cho viec hoc tap, nghien cu ve phan mem (chng trnh). e tien hanh mo phong vi ieu khien chung ta phai khao sat cac ho vi mach ma ta s dung, sau o tien hanh ve mach (phan cng) va nap chng trnh (phan mem). Chng trnh nap cho vi ieu khien la nhng file co uoi cham Hex, phan cng va phan mem phai c lu vao cung mot th muc.

e nam vng cach mo phong ta tien hanh cac v du minh hoa sau.

1. Mo phong mach ieu khien ong c bc: ong c bc la ong c ong bo. No c dung rong rai trong lnh vc

c kh chnh xac va t ong hoa. ong c bc thng co 4 pha ieu khien va 2 pha chung dung e noi len nguon hay suong mass tuy vao cach ieu khien. ieu khien ong c co 2 cach o la ieu khien bc u va na bc. Mach mo phong sau se mo phong ong c theo bc u.



S o mach mo phong:

e ve c mach mo phong nh tren ta tien hanh theo cac bc sau ay: Bc1: Vao th vien Micro lay vi ieu khien AT89C51 loai bus.



Bc 2: Vao th vien Analog lay Ic 2003

Bc 3: Vao th vien Active lay ong c bc,au do logic (Logicprobe Big) va Logictoggle.



Bc 4: Cac linh kien c chon nam trong ca so Divice selector, ta click vao linh kien can chon va click vao vung ve mach.

Sau khi chon tat ca cac linh kien ra vung ve mach ta c nh sau.

e lay nguon cho mach ta vao bieu tng Inter_sheet Terminal ,

sau o trong ca so Device Selector ta chon Power sau o click vao vung ve mach.

Vung ve mach



Bc 5: Tien hanh noi day cho cac linh kien. e noi day ta ch can a chuot en chan linh kien can noi th nhat, sau o click vao chan linh kien th hai can noi en. Isis ho tr t ong i day. Sau khi noi day hoan chnh ta c s o mach nh sau.

Bc 6: Nap chng trnh cho vi ieu khien. e nap chng trnh cho vi

ieu khien ta click chuot phai vao vi ieu khien cho no o len sau o lick chuot trai vao no mot lan na e vao ca so Edit Component.



Trong ca so Edit component co hai muc can chu y: Muc Program file e nhap ng dan en chng trnh can nap.

Muc Clock Frequency dung e chon tan so lam viec cho vi ieu khien. Tan so chon phai u nho e co the quan sat hoat ong cua mach.

Bc 6: Chay mo phong. e chay mo phong ta Click vao bieu tng

.

Khi mo phong ta co the quan sat cac trang thai logic ngo ra ieu khien ong c bc thong qua cac au do logic.



e quan sat dang xung ieu khien ta co the s dung cong cu Simulation Graph sau o chon phan tch tn hieu so ( Digital Analysis). Cong cu nay a c trnh bay kha ro phan mo phong so.

e ieu chnh ttoc o cua ong c ta thay oi tan so lam viec cua vi ieu khien.

Mot iem can lu y la khi lu mach mo phong ta nen lu vao th muc cua chng trnh cai at(C:\ProgramFiles\LabcenterElectronics\Proteus 6 Professional) va phan mem cung c lu vao ay (cung mot th muc).

2. Cach s dung Sample Design:

Sample design la phan nam trong menu Help cua ISIS. Trong sample design co cha rat nhieu v du minh hoa. Chung ta co the da vao nhng v du nay e tm hieu, hoc tap cach s dung phan mem.

Trong ca so Proteus Sample File co 4 muc e ta chon la:

Schematic And Pcb Design Samples: trong phan nay cha cac v du ve ve s o nguyen ly va s o mach in.

InterActive Simulation Samples: trong phan nay cha cac v du phuc vu cho viec hoc tap, cac thiet b ao va cac mach em.

Graph Based Simulation Samples: trong phan nay cha cac mach s dung cac bieu o e phan tch tn hieu so va tn hieu tng t.

Microprocessor Simulation Samples: trong phan nay cha cac mach s dung vi ieu khien e mo phong.

Proteus Vsm Tiny Chess: mach mo phong c vua.



Trong phan Microprocessor simulation sample chung ta se thay co rat nhieu v du ve mo phong vi ieu khien nh : ADC_DAC, LCD, STEPPER..

Cac v du minh hoa trong Sample Design c trnh bai rat ro rang, chung ta co the thay oi cac thong so trong mach mo phong mot cach de dang. Ngoai ra chung ta con co the oc c chng trnh (phan mem) trong cac v du minh hoa. Ban co the copy nhng phan mem nay e tm hieu cach lap trnh (ngon ng Assembly) cua nha san suat.

Cach oc phan mem nh sau:



Khi ta m mot v du trong Sample Design chang han nh chung ta m v du ve mo phong ADC.

Sau khi chon v du mo phong ta vao bieu tng Sourse tren thanh Menu e vao m phan lap trnh cua nha san suat.



Sau khi m file ADC.asm ta thay xuat hien noi dung sau.

ay la noi dung cua chng trnh (phan mem). Neu chung ta copy toan bo file nay cho qua chng trnh SPKT sau o bien dch sang file hex th co the nap vao cho vi ieu khien.
